IMAGING SYSTEM WITH ADJUSTABLE OPTICS

摘要

This invention provides a solution for determining a non-exposure time during which imaging optics can be adjusted without affecting the image being captured. In the solution an image sequence comprising at least two images is acquired, at least one of which said at least two images is used as measurement image and at least one other of which said at least two images is used as final image. Exposure times are determined for the measurement image and the final image. By means of the exposure times for the measurement image and the final image, the non-exposure time can be determined. As a result of this, the imaging optics can be adjusted during non-exposure time.
